and useful Improvements in HayCarriers, of

which the following is a specification.

My invention relates to certain improve ments in hay-carriers of theclassin which a track and traveler thereon are used in conf nection witha carrying device suspended from the traveler by means of a rope or itsequivalent, the rope being utilized both to lift the carrying device andto move the traveler along the track. More particularly it belongs tothe class of carriers in which means are" provided for locking the ropeto the traveler at any desired point, so that the load need not belifted any farther than is necessary to clear obstructions in'its path.

The main object of the invention is to provide a simple and' effectiveclamping device for the main rope operated bythe rope itself, so thatthe clamping action maybe proportional to the load. In this Way the ropewill be gripped lightly with a light lload and more strongly with aheavy load, and the wear and tear upon the rope and operating deviceswill be only such as is necessary at alltimes.

To this end the invention consists in a certain novelgripping devicearranged in proper relation to the rope and in certain minor andincidental features of novelty used in cornbination therewith for themore effective accomplishment of the purpose, desired.

In the drawings, Figure l is'aside elevation of a complete carrier.vrFig.`2 is a similar view with one of the side plates removed and thecentral carryingfplate cut in the line 2 2 of Fig. 3. Figg is ahorizontal section looking downward from the plane 3 3 of Fig. I. Fig. 4is an enlarged vertical section in line 4 4 of Fig. 3. Fig. 5 is atransverse vertical section in line 5 5 of Fig. 4. Fig. 6 is atransverse vertical sectionin line 6 6 of Fig. 4 looking in thedirection of the arrow 6; and Fig. 7Ais a longitudinal vertical sectionof a trigger and operating-spring, the location and use of which will behereinafter fully set forth.

Referring to the drawings, the track is shown at A and the carrier-frameat B, the

latte-r being provided with wheels b, running upon the track A. yThetraveler is provided with a circular plate b below the track, aboutwhich is secured a turn-table C, carrying two downwardly-extending sideplates c c', spaced apart by means of perforated gudgeons c2 'c3 c4 c5and by a strut c6. Bolts c7 clamp the two side plates together at all ofthese places, and

the gudgeons 'are used as bearings for the various workin g partsbetween the two plates. The strut c6 is notched at cs upon its underside, and a locking-lever D, pivoted upon the gud geon c3, is providedwith an end d, adapted 'to swing upward toward the notch and bind ythemain rope between said end and the strut. Said lever carries between itspivot and its opposite end a pulley E and beyond said pulley is providedwith a bolt d', working in a slotf in a dog F, pivoted upon the gudgeonc2. Said dog is provided withalugf, in position for engagement with theshort end g of a trigger G, pivoted atg between-the plates and providedwith a spring g2, bearing upon the plate b and tendingto hold thetrigger in the position seen in' Fig.Y 4. In this position it will benoticed that the end d of the locking-lever D is held awayfrom the strutc6. The parts are shown inthe same position in Fig. l, which alsoshowsthe rope H secured to the traveler at h and extending downwardtherefrom in the form Vof a loop, upon which are shown a pair of pulleysI I, adapted for use with an ordinary hay-sling. The rope also passesover thelpulley E upon the locking-lever and a guide-pulley J, journaledupon the gudgeon c4. IVhen the parts are in the position shown in saidFigs. l and 4, the rope is free to pass over the pulleys E J to lowerand raise the carryingpulleysl`I', as is done whenever a load is to bepicked up. A stop a upon the track holds the travelerstationary at thistime, so thatthe rope may have no tendency to move the latter upon thetrack. For this purpose the dog'F extends upward from the pivot and isprovided with two fingers fzj'i, adapted to engage the opposite sides ofthe stop. It should be noticed that the weight of the load is sustainedby the pulley E through the medium of the rope H and that said loadpulls downward uponl the left-hand side of the dog F, tending to `drawthe fingers fif3 away from the stop and at the IOO arranged in suchposition as to be engaged by the frames of the `pulleys I I' when theload is drawn up to the carrier. device consists of a rope M, secured tothe end g3 of the tripping-lever, passing upward therefrom over a pulleycb upon one of the side plates, and then downward to a sufficient extentto enable it to be easily reached by the person who attends to theloading of the carrier. The yoke K acts automatically to release thetraveler and grip the rope when the load is drawn upward as far as theparts will permit. The hand rope M provides means for manually trippingthe carrier to release it from the track-stop and to grip the rope atany point desired. The tightness of the grip upon the rope is directlyproportional to the load, inasmuch as it is the weight of the load whichpresses the gripping-lever against the rope. f

In the operation of the device, starting with the position shown in Fig.l, the rope is given suiicient slack to enable the sheaves I I to pickup the load, after which said load is drawn upward by means of the ropeH until suiciently elevated to clear all obstructions. If this point isreached short of the limit xed by the parts, the carrier is tripped bymeans of the hand-rope M, releasing the dog Ffrom the track-stop a a-ndpermitting the traveler to be drawn by the rope in the directiondesired. After the load is discharged the carrier is returned to theposition shown, and as it reaches this position the track-stop a engagesthe iingerfs, tilting the dog until the trigger G engages the lug f,locking the parts again until released, as before. Vhenever it isnecessary to raise the load to the limit the hand-rope is not operated,but the tripping of the carrier is accomplished by the contact of thesheaves I I with the shoe 7a2.

Looking at Figs. 2, 4, and 5 it will be seen that the dog F is the onlyobstruction to the movement of the traveler beyond the trackto the plateb.

The second the lower part of the traveler may be turned to remove thedog F from the path of the track-stop and also to reverse the positionof said dog and bring it upon the opposite side of said traveler.

I believe the invention in its broadest construction is independent ofthe exact form or combinations of devices by means of which it isattained, and for that reason I do not limit myself to the specificconstruction above shown and described.

I claim as new and desire to secure by Letters Patentl. The combination,in a carrier of the class described, and with a traveler and draft-rope,of a lever pivoted between its ends to the carrier, a bearing upon thecarrier opposite to one end of said lever and adapted to coact with saidend to clamp the rope between the two, a pulley over which thedraft-rope runs, journaled upon said lever, upon the opposite side ofthepivot from the clamping end, means for raising and locking said pulleyin its raised position and means for tripping the lock to release thelever; substantially as described.

2. The combination, in a carrier of the class described of a traveler, adraft-rope, a bearing upon the carrier, a lever pivoted between its endsto the carrier and having one of its ends arranged to grip the ropebetween it and the bearing, a pulley upon the lever upon the oppositeside of the pivot and arranged to carry the draft-rope,devices foroscillating the lever upon its pivot, a trigger adapted to lock thelever away from the draft-rope and means for pulling said trigger andreleasing the lever; substantially as described.

3. In a carrier of the class described, the combination with a suitabletraveler and a framework suspended therefrom, of a lever pivoted betweenits ends to the carrier, adapted to grip the rope between one of itsends and a portion of the frame, and having a pulley upon its oppositeend, a draft-rope running over said pulley, a track-operated dog`connected with the pulley end of the lever y and adapted to raise it, atrigger arranged to engage the dog, when the lever is raised and meansfor actuating the trigger to release the dog and the lever 5substantially as described. In Witness whereof I have hereunto set my'hand at Harvard, in the county of McHenry and State of Illinois, this9th day of December, A. io. 1899.
